Say this
- Treat every roof as fragile until someone competent tells you it is not. That includes skylights, plastic sheets and old cement sheets.
- Never walk along the bolt lines. Old repairs can have bolts with nothing under them.
- Only use the access we set up. Ladders must be tied and stick up a metre above the gutter.
- Stay on the crawl boards or staging. If you lift a sheet, cover the gap before you walk away.
- Clip your harness only to the anchors we checked this morning. Not to a vent pipe or a gutter.
- Nobody goes on a fragile roof alone. Your buddy raises the alarm if you go through.
- If it rains, come down and wait. A wet roof is a slide.
Ask the crew
- Which parts of today's roof are fragile, and how do you know?
- Where are the anchors you will clip to?
- What do you do with the gap when you remove a sheet?
- Who is your buddy on the roof today?
Show them
- The warning sign at the roof access point and the fragile areas on today's roof.
- A crawl board fixed with its ridge hook, and the lifeline beside it.
- A correct opening cover marked HOLE or COVER.
